Just used these guys for a custom stainless Goodridge hose to fit the rear of my 11S, I was only £24 which is cheaper than a standard hose on ebay
They've got shedloads of stuff for just about anything on wheels and if their customer service I got is anything to go by, you'll not be dissapointed
Email Russ on their contact page if you've got a custom request, They actually reply, unlike some other mail order companies, M&P Direct for example
